Could do just little things that keep the link there... viewing this long term of course but friendships can have rocky patches... there may be times you seriously piss each other off and need a break... so just give them some room for now.

A way I kept friendships going were greetings cards... birthday and Christmas. One of my mates is a self confessed friendship wrecker and this year admitted that he'd not shaken me (and our 4 other friends that I don't have to work quite as hard with) off due to me keeping that small little tie and the odd text message going now and again (we've been mates for going on 30 years).

So, yeah... perhaps just let things simmer down, let the irritation or anger calm and just send a card hoping they are ok and that you're thinking of them... nothing clingy or dragging up past crap... just drawing a line and moving forward Don't expect anything back at first... might take a couple of years... but, if they mean a lot to you... it's just that little prod to show you still think of them
